Assessment measures of Health-Related Quality of Life (HRQoL) of migrants: a systematic review

Purpose - Definition-problems concerning the terms "migrant" and "Health-Related Quality of Life"(HRQoL) have a negative impact on the operationalization and measurement of the multidimensional and subjective construct of HRQoL. The aims of this systematic literature review are to address the following questions: How can the instruments used within the research field "migration and HRQoL"be described or categorized? Which dimensions (psychological, physical and social) and associated sub-dimensions have been used concerning measuring HRQoL when measures are applied to migrants? Design/methodology/approach - A systematic review was conducted. Three databases (Medline, Embase and Cinahl) were systematically searched for the investigation on HRQoL of migrants. Articles written in English, German and Polish, published since 2003 and meeting other inclusion criteria, were included in the final analysis. Findings - In the first stage a total of 4,062 studies were identified. However, very few studies were found to focus on HRQoL among migrants. Finally, 28 studies were included in the analysis. The results confirm that the terms "migrant"and "Quality of Life"and "Health-Related Quality of Life"are neither congruently used nor defined, respectively, within these studies, which consequently impacts deleteriously on the application and measurement of the concept in these groups. The majority of the studies reported to measure HRQoL with a well-known and validated HRQoL instrument. The physical dimensions (symptoms/pain/vitality, energy/vitality/sleep and the objective/subjective health status) are predominantly represented in the reviewed literature. The psychological dimension mostly includes sub-dimensions such as psychological stress and depressive symptoms; the social dimension was predominantly considered as the sub-dimension social relationships/networking. Originality/value - This paper highlights profound issues in the accurate assessment of HRQoL in migrants. This may have a significant impact on delivery of appropriate evidenced-based care for migrants in need of healthcare intervention.
